The Earth's land surface is dominated by sloping landscapes. Every year, soil erosion laterally distributes on the order of 75 Gt of topsoil (Berhe et al. 2007). The coupled biogeochemical cycles of ...

Researchers have unveiled crucial details about how a common freshwater bacterium, Methylobacter sp. YHQ, manages the ...

Soil erosion is widely known for degrading land and reducing agricultural productivity. But new research shows it may also play a far more complex and important role in regulating the global nitrogen ...

The nitrogen cycle is a biogeochemical process encompassing the biologically mediated and abiotic transformations of nitrogen between atmospheric, terrestrial, and aquatic reservoirs, enabling its ...

The Wang Stable Isotope Biogeochemistry Lab at Boston College uses stable isotope analyses to investigate the biogeochemical cycles of both modern and past oceans and to examine their implications for ...

Earth’s Mantle Nitrogen Content Is Comparable To That Found In Its Nitrogen-Rich Atmosphere. Mantle Nitrogen has been proposed to be primordial or sourced by later subduction, yet its origin has not ...

Nitrogen may not get the same level of attention as its neighbors on the periodic table, carbon and oxygen. But like its neighbors, it's an element we can't live without. Nitrogen compounds have ...
